09 225 opti has low voltage fault code
Getting a sensor supply voltage low B code #602-5 From what I have read the pcm is possibly faulty in sending out the 5v to the sensors. I have another pcm to swap but don't want to swap out if there is a possibility of sending another one to the trash pile. Any advice? Batt and wires good.

Can you put your pcm on another Opti and see if you get the code? Otherwise Simon/Brucato/Powers must test PCM's?

Yes, I can swap pcm's but am wary to do it thinking the engine may have a problem that could fry the second pcm too.

Mines a down draft...Ser. no 1B780484 09 225 opti. I may just bite the bullet and take it to the dealer to be scanned. Lot of variables. Could be a sensor, or computer, or I dunno....Had a long beep and went into guardian mode when trying to 1st plane it out. Shut it off, re-started it and ran all day with no issues or beeps. I have a merc monitor that reads on my phone and gave the code and problem.

I sleuthed it down to the trim sensor being the culprit. Pulled it and all's well. Did the trick of swapping the pcm and found it to be good. Darn opti's are the strangest engines....
